I'm having the same problem. I saw on the developer's blog that it can be caused if you are using Google's two-step verification, but I'm not and still can't get it to sync, so I have no idea. I sure do want it to work!

I guess I could be using it wrong but I paid for Glimpse and I don't even use it.
I must be missing the point or something. I sometimes use it for my twitter feed. I don't like the way it displays my google reader and I can't access my bookmarks in the browser as far as I can tell.
So, for a program that is supposed to make me more efficient it's actually doing the opposite.

You can't access your browser bookmarks, because it's impossible for 3rd party Apps.
I'm sorry you haven't found a use case scenario (yet). Some people like using it for RSS/Twitter/Web (my personal favorite). Some People use it for their multiple twitter accounts (you can have up to 5 different accounts open in each pane). Some people use it for watching Youtube while keeping an eye on their twitter feed.
One thing to keep in mind, each mini-app (or widget as I call them), isn't meant to be a full feature app (otherwise, the App would cost more than $5 ) They're meant to be 'light-weight', just enough to get the basic stuff done. If you're a twitter junky, even though the twitter widget is quite full-featured, you're probably better off using SpazHD. If you're looking for a more immersive google reader experience, you're probably better off using NomNomNom or any other dedicated App.
